i have an 89 bronco2 2.9 fi 4x2 5speed ok i want a 4x4 and i dont know if i should find something or try to make it a 4x4 and if so how would i go about that

If you realy like your truck you can find a 4x4 donor in the junk yard and take the front end and transmission ans transfer case out of it.

I have a 1990 Bronco II 4x4, 5speed, 2.9L that you may be interested in.
It's been started and driven around the yard for the last two years and needs a good home.
I'm located outside of Philadelphia if interested.
